To cum inside some sort of pastry and give it to some one as a present, when they take a bite they will be quite surprised.
SFJ: You know when you're fucking a pastry and instead of pulling out you just bust right in there?

SFR: No, but lets just say I do.

SFJ: Well you just keep it for while then give it to some one for, like, they're birthday or some shit.

SFR: And people atcually do this?

SFJ: It's the double stuff surprise, man.
